Be “environmentally friendly” to your equipment’s electrical components — specify the correct enclosure type.

In addition, enclosures provide varying degrees of protection against the external environment. Approval of electrical equipment enclosures for the environment is a requirement of the National Electrical Code and critical to the long-term performance of hvacr equipment.
